JOHN DESMOND, OF CLEVELAND, OHIO, ASSIGNOR TO SIMON & ONEILL, OF SAMEPLACE.

STEAM-INJECTOR.

SPECIFICATION forming part of Letters latent No. 326,408, datedSeptember 15, 1885.

' Application filed June 1, 1835. (ModeL) To aZZ whom it may concern.-

Be it known that I, JOHN DESMOND, a citizen of the United States ofAmerica, residing at Cleveland, in the county of Cuyahoga and State ofOhio, have invented certain new anduseful Improvements inSteam-Injectors, of which the following is a specification, referencebeing bad therein to the accompanying drawings.

My'invention relates to an improvement in steam-injectors; anditconsists in the peculiar construction, combination, and arrangement ofits parts, by which its action is rendered automatic, substantially ashereinafter more fully shown and described.

In the accompanying drawings, Figure l is a side elevation of mysteam-injector. Fig. 2 is a central longitudinal section.

In constructing my steam-injector, chamber A, having steam-inlet pipe B,transverse walls C and D, and water-supply pipe E, is east integral withchamber F, having overflow pipe G. The passage-way between thesechambers consists of a tapering tube, J, a tube, H, and steam-duct I,the latter being cast integral with one side of the injector, and isslightly curved at one end thereof. Steamrduct l and chamber A areconnected by a coincident orifice at I, and duct I and chamber F are inlike manner connected at I The wall C of chamber A is provided with athreaded orifice, wherein is inserted the correspondingly thread ed andtapering tube J, and in asimilarorifice in wall D of said chamber tube His in like manner inserted. The tube J is also made flaring, the largerend thereof being arranged in line with the threaded steam-inlet pipe B,in order the better to receive the full force of the steam.

Chamber F having opening therein, overflow-pipe G, as aforesaid, isdivided into compartments. WVall a, having centrally disposed thereinthe tapering tube 12 and valve d, also serves to separate chamber A intocompartments during the flow of the water into the boiler, at which timethe valve (1 is closed by the condensed steam against the innerperipheral flange, a, also formed integral with chamber F.

Valve (2 consists of the disk d, having the radiating lugs d immediatelybeneath the same and integral with its tubular valve-rod e. The tubularvalve-rod e is also provided with the transverse orifices e, and themouth of the lower end of the tube is tapered to eon- 5 form to thetaper of tube 12. The valve-rod e is also fluted longitudinally at f,the fiuting terminating at one end in a disked shoulder,

g, forming the bearings of the elastic washer h, and valve-rod e is alsoencircled by packing-ring 2', having shoulder i, which is tightlysecured in place by means of the nutj, which has an orifice providedcentrally therein for the valve-rod tube k, having cap L, wherein playsthe valve-rod e.

Chamber A being filled with water, the water is forced by pressure ofthe steam through the tube 12 toward the boiler, and as the steam whichpasses through the curved du ct I comes into contact with this water itis 0 forced into the boiler, and when the boiler is filled the valve,,dascends and the overflowwater finds egress through the overflow-pipe Cr.

Having thus fully described my invention, what I claim, and desire tosecure by Letters 7 5 Patent, is

1. The combination, with the chambers A and F, the tubes J, H, and b,and the overflow-pipe G, of the valved and the steam-duct I, the latterlocated on the outside of the outer wall of the injector, substantiallyas shown and described.

2. In a steam-injector, the steam-duct located on the outside oftheinjector and opening into chambers A and F, in combination with thevalve d and the overflow-pipe G, the whole arranged to permit thesimultaneous lifting and forcing of a supply of water, substantially asshown and described.

In testimony whereof I affix my signature in 0 presence of twowitnesses.

JOHN DESMOND.
